What you will need:
-a 13" MacBook Pro from 2010, 2011, 2012
-two matching RAM chips
-small glass jar or other small container
I upgraded my RAM at TechShop Menlo Park. They had all the tools that I needed to complete the job, and they have lots of people who work and/or hang out there that are very knowledgeable and helpful in case anything went wrong with my installation.
Step 1: Buy Your RAM
There are a lot of rumors going around on the interwebs claiming that the MacBook Pro's that are listed as having 8GB memory restrictions can really handle 16GB. I thought about upgrading to the full 16GB, but a few things deterred me from the 16B. Number one, I am afraid of my computer overheating. Second, I was worried that my battery life would suffer with the extra RAM. And finally, there must be some reason that apple doesn't recommend using the full 16GB. A computer company would love to advertise a 16GB maximum rather than an 8GB maximum because that would mean that a computer has more potential, I think they would only limit the advertised max to 8GB if there was good reason.
